I put new torrent files weekly. Mostly TV shows, latest episodes of sitcoms, etc...
They play without any problem using the stock player. In fact, now that I think about it, not once a video fail to run.

well im at my wits end with it all , tryed every thing now for almost 2 days. I even rooted my phone so I could mount my SD as mass storage as thought it may have been MTP's fault. I'm out of ideas now.

ok so in another twist , after trying to put another film on it turns out I cant transfer via usb cable , I must take out my micro sd and pop it in a card reader and do it that way. Even tho music is ok , films it seems is a no no WTF !

Could happen in few cases. If the file is large and stored on external drive. Moving it from drive to drive via PC, especially larger files, can time out.
Either of the storage is not fast enough.
The SD card could simply be too slow or faulty, incapable of processing large files. I have ridiculously expensive, top range sandisk extreme pro, which cost me like 150$, but I can move few DVD quality AVIs. faster than on my 1TB external hard drive.

I would strongly recommend testing another card, or use smaller one, like 32gb. They seem to be less problematic.
